BUILDING W'ALL.

Applieation'flled September 8, 1925. Serial No. 54,994.

This invention relates to improvements in' buildin walls.

An ject of the invention is to provide an improved building wall construction which may be formed of self-hardenin plastic material such as concrete and whicfi will not require the use of wooden forms or the like. I

The improved wall consists'essentially of two parallel walls constitutingthe forms for. the concrete.

or built up of tiles or slabs and the selfhardening material-is poured between them, so that when the material hardens the two parallel walls formed of the tiles form the exterior surfaces of the wall.

With the foregoing and other objects inview which will be made manifest inthe following detailed description and specifi- 2 cally pointed out in the appended claims, reference is had to "the accompanying drawings for an illustrative embodiment of the invention, wherein, 5 Figure 1 is a partial side elevation of the wall of the improved construction.

. Referring to the accompanying drawings wherein similar reference characters designate similar arts throughout, the improved 5 wall may be uilt upon an suitable foundation such as indicated at It consists of is a perspective view illustrating one, of the sheet metal contwo parallel walls indicated at 10 and 11 respectivel which walls are formed or built: up of t' es T. Thetiles are arrangedv in 5 horizontal'courses and have theirvertical 'oints broken or staggered as clearl shown in Fig. 1. Preferably the tiles on 0th the f inner and outer walls are directlyopposite ""each other so that the vertical joints of corresponding courses forming the two walls will be upon the same transverse planes.

These walls are formed Fig. 3 is a vertical section taken upon the,

ranged between the In the preferred form of construction the tiles have bead and groove joints between each other and as clearly shown in Figs. 5 to 8 inclusive, the top and one side edge of eachof the tiles have beads 12 formed thereon and the opposite side edge and the bottom edge have grooves 13 formed thereon,

so thatwhen the tiles are assembled the 7 within the grooves of adjacent tiles.

Sheet metal connectors which serve also as reinforcing members, such as 14: are ar- "ranged vertically between the courses and opposite alternate course's. These sheet metal connectors are provided with extensions 15 which are crimped as indicated at,

16 complimentar to the beads-and grooves formed on the ti es. The extensions 15 are arranged between the vertical joints between the tiles and in this manner the connectors keep the inner and outer walls in properspaced relation while the self-hardening plastic material such as concrete 0 is poured between the walls. The sheet metal connectors. referably extend from top to bottom of t e walls, altlfough they, may be formed of sections if found desirable. When. the inner and outer walls are built up and the sheet metal connectors are in place the concrete C is poured between the walls imbedding the connectors therein.

When the concrete hardens the walls are connected together by it and the tiles are connected to each other. These tiles remain irf place and form the outer surfaces of the wall so constructed. If desired the tiles may be tinted or be ornamented in any de-. sired manner.

From the above described constructionit will be readily appreciated that it is unnec essary toconstruct the conventional wooden forms in forming the wall and the blocks or tiles can be formed at some central molding plant and shipped to the job where they can be easily and quicklyset up with the connectors, and the concrete then poured.

Not only doesthe improved construction eliminate the use of forms. but italsoprovides for an o upon the wall if desired.

' If at I an 7 hollow wal construction .it will be readily appreciated that suitable cores. can be ar innerand outer walls and between the sheet metal connectors.

When the concrete; is poured it pouredrnamental finished appearance time a is wished to form a i I defined by the appended claims.

What I claim is:

1. A building wall comprising two walls built up of horizontal courses of tiles, having vertical joints broken or staggered, said tiles having bead and groove vertical-joints,

sheet metal connectors positioned between the walls in vertical position, having crimped extensions positioned between the vertical joints of the tiles of alternate courses, and a self-hardening plastic material disposed between the two walls imbedding the connectors therein.

2. A building wall comprising two walls built up of horizontal courses of tiles having vertical joints broken or staggered, sheet metal connectors positioned between the walls which are more than two courses high, said connectors having extensions between the 'oints of the tiles of alternate courses, an a self-hardening plastic material disposed between the two walls, imbed- (ling the connectors therein.

In testimony whereof I have signed my name to this specification.
